Charla: Safer Flight Systems using Distributed Dynamic Data-Driven Avionics

Te invitamos el próximo 21 de junio a la Charla: Safer Flight Systems using Distributed Dynamic Data-Driven Avionics. 


01 06 varelaC1

Dynamic data-driven avionics can improve situational awareness in flight emergencies when pilots need to make decisions very quickly to maximize the chance of a safe outcome.  

For example, sensor data errors can lead to catastrophic accidents.  Air France 447’s accident was initially due to pitot tubes icing resulting in incorrect air speed data. Tuninter 1153’s accident was caused by the installation of a wrong fuel quantity indicator.  We propose a dynamic data driven approach to detecting erroneous data produced by failing sensors, and when possible, we recover the data from redundant data streams.  We describe mathematical concepts and software we have developed to tackle this challenge, including a dynamic Bayesian approach to learn failure models from data.

We will also discuss a Dubins curves-based approach to creating safe gliding trajectories after engine failures, such as in the US Airways 1549 incident over the Hudson River, or the more recent Southwest 1380 flight which landed in Philadelphia.  A dynamic data-driven approach can use sensor data to more accurately model a damaged airplane’s performance and provide plausible flight plans to pilots and air traffic controllers.

Finally, we introduce the notion of a Virtual Sky, a distributed application that could use ADS-B data broadcast by aircraft including real-time weather and air traffic, effectively forming an Internet-of-Planes.  We will address challenges in the formal verification and validation of these distributed dynamic data-driven avionics systems.
